The anguished mom whose unarmed National Guardsman son was shot dead by an NYPD cop last year called for a federal probe of the killing today after a Queens grand jury declined to bring criminal charges against the detective.

“He is still a murderer no matter what in my eyes,” Cecelia Reyes said of Det. Hassan Hamdy who fired a single fatal shot at the 22-year-old driver, Noel Polanco, early on Oct.4 near LaGuardia Airport, following a high speed chase on the Grand Central Parkway.

“I’m sure he is a parent, and I wish he understood it the way I do. You need to use your mind before you do something like this. Someone in a position like this should think before they use their gun. It’s still murder to me. It’s still murder,” she said.

Speaking at Rev. Sharpton’s National Action Network in Harlem, Reyes added, “Where was the weapon? Why couldn’t he just use his head and say…’License and registration?'”

The distraught mom said she was pursuing legal action to stop the Emergency Service cop from killing anyone else.

“I am so afraid that he can hurt someone else or do something to someone else. If I could put a stop to that, I would,” she said. “I’m not giving up. I’m going to continue to fight.”

The detective claimed he fired his gun thinking that Polanco was reaching for his weapon underneath the seat of his Honda Fit. But it wasn’t a gun–police said they recovered a mechanics drill from under the seat.

Polanco’s passenger, Dianne DeFerrari, insisted that her friend never took his hands off the steering wheel after he was pulled over for driving recklessly. A second passenger, a female NYPD cops was asleep in the back seat, awoken by the sound of a bullet blast.

Reyes attorney, Robert Mijuca, said that in addition to asking the feds to start their own civil rights violation probe, the family would file a notice of claim next week against the city and the NYPD, the first step in a civil lawsuit.

The grand jury decision was announced on Thursday, but the detective still faces an internal NYPD probe.
